Abstract
The utility model discloses adjust automatically connecting shafts, including left and right screw rod, the head of left and right screw rod has outer-hexagonal head, equal screw thread is screwed with locking nut on the screw rod of left and right, it is characterized by: the centre of left and right screw rod is equipped with coupling sleeve, the inner hole of coupling sleeve carries out necking respectively in left and right port position to form the limit baffle ring of left and right, left and right nut set is movably equipped in the inner hole of coupling sleeve, the left side of coupling sleeve is stretched in outside the left end of left nut set, the right end of left nut set is equipped with the first flange and is blocked by left limit baffle ring, the right side of coupling sleeve is stretched in outside the right end of right nut set, the left end of right nut set is equipped with the second flange and is blocked by right limit baffle ring, it is left, the centre of right nut set is equipped with compressed spring, the left screw flight is connected to left nut and puts on, the right screw flight is connected to right nut and puts on.The utility model can carry out elastic connection, to realize the adjust automatically of position between two connected pieces, and solve the problems, such as connected piece structure is complicated.
Description
Technical field
The utility model relates to a kind of connection parts of automobile, and in particular to a kind of adjust automatically connecting shaft.
Background technique
Connecting shaft is equipped with after automobile in arrester, the pattern of connecting shaft there are different structure designs according to vehicle.A kind of company
Spindle, including left screw rod and right screw rod, the centre of left and right screw rod are equipped with thread bush, and left and right screw rod carries out screw thread with thread bush respectively
Connection, it is different by the depth of left and right screw rod precession thread bush, to realize the adjustment of connection shaft length.The connecting shaft of above structure
Although adjustable in length not can be carried out elastic connection, so can not achieve the adjust automatically of position between two connected pieces, and
Need to be arranged on connected piece elastic connection structure, the structure of connected piece can be complex.
Summary of the invention
In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide one kind can carry out elasticity even
It connects, to realize the adjust automatically of position between two connected pieces, and solves the problems, such as that the connected piece adjust automatically that structure is complicated connects
Spindle.
For this purpose, the utility model adopts the following technical scheme that realize:
Adjust automatically connecting shaft, including left screw rod and right screw rod, the head of left and right screw rod have outer-hexagonal head, left and right spiral shell
Equal screw thread is screwed with locking nut on bar, it is characterised in that: the centre of left and right screw rod is equipped with coupling sleeve, and the inner hole of coupling sleeve is on a left side
Right output port position carries out necking respectively to form the limit baffle ring of left and right, is movably equipped with left nut set and the right side in the inner hole of coupling sleeve
Nut set stretches in the left side of coupling sleeve outside the left end of left nut set, and the right end of left nut set is equipped with the first flange by left limit
Baffle ring is blocked, and stretches in the right side of coupling sleeve outside the right end of right nut set, the left end of right nut set be equipped with the second flange by
Right limit baffle ring is blocked, and the centre of left and right nut set is equipped with compressed spring, and the left screw flight is connected to left nut set
On, the right screw flight is connected to right nut and puts on.
The adjust automatically connecting shaft of above-mentioned technical proposal, left and right screw rod connect with two connected pieces respectively and use locking nut
It is locked, since the left and right nut set that the thread bush of the prior art is coupled set and is movably arranged at coupling sleeve inner hole is replaced,
And compressed spring is arranged in the intermediate of left and right nut set, therefore the adjust automatically connecting shaft of the utility model can be to two connected pieces
Elastic connection is carried out, not only realizes the adjust automatically of position between two connected pieces, but also two connected pieces do not need yet simultaneously
Elastic construction design is carried out, structure is complicated to also just solve the problems, such as two connected pieces.
Preferably, the coupling sleeve is partly closed up and is fixedly connected up and down by independent.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the structural schematic diagram of utility model.
Specific embodiment
As shown, the adjust automatically connecting shaft of the utility model, including left screw rod 2 and right screw rod 8, the head of left and right screw rod
Portion has outer-hexagonal head 1, and screw thread is screwed with locking nut 3 on the screw rod of left and right, and the centre of left and right screw rod is equipped with coupling sleeve 5,
The inner hole of coupling sleeve 5 carries out necking respectively in left and right port position to form left limit baffle ring 51 and right limit baffle ring 52, described
Coupling sleeve 5 is partly closed up and is fixedly connected up and down by independent, is movably equipped with left nut set 4 and the right side in the inner hole of coupling sleeve 5
Nut set 7, stretches in the left side of coupling sleeve 5 outside the left end of left nut set 4, the right end of left nut set 4 equipped with the first flange 41 by
Left limit baffle ring 51 is blocked, and the right side of coupling sleeve 5 is stretched in outside the right end of right nut set 7, and the left end of right nut set 7 is equipped with
Second flange 71 is blocked by right limit baffle ring 52, and the centre of left and right nut set is equipped with compressed spring 6, left 2 spiral shell of screw rod
Line is connected on left nut set 4, and the right screw rod 8 is threadedly connected on right nut set 7.
Claims (2)
